LEE ANDREW TETER, OFGANTRIL, IOWA.

srLAGE-PAcK-ER.

To all whom it may concern; Be' it known that I, LEE A, TETER, a citizenof the United States, residing at Cantril, in the county of Van Burenand State of Iowa, have invented new and useful. Improvements inSilage-Packers, of which the following isa specification. This inventionrelates to new and useful improvements in :ensilage packing devices forsilos and the principal object of the in vention is to provide a deviceincluding rollers for traveling over the ensilage and supporting anengine for driving the device and adding to the weight thereof toincrease the packing effect.

Another object of the invention is to provide an automaticallyadjustable roller'for packing the ensilage adjacent the silo wall whichis out of the path of the main rollers.

A further object of the invention is to pro vide means for adjusting theposition of the conical roller to accommodate the device to differentsizes of silos.

Another object of the invention is to provide a device of this characterwhich is simple and durable in construction, reliable and eflicient inoperation and one which can be manufactured and placed upon the marketat a minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims. I

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which l Figure1 is a plan view of the invention.

' Fig. 2 is an elevation thereof.

Fig. 3 is a view of the front or small end.

Fig. 4 is a cross section on lme 4-4 of F ig. 1 shbwing the means foradjusting the conical roller.

Fig. 5 is a detail showing one of the brackets engaging with the packingroller.

Fig. 6 is a view of the rear end.

As shown in these views the frame of the device is composed of twoelongated bars 1 slightly convergent and having their front endsconnected together by a block and their rear ends bolted to a bolster 2,said bolster extending beyond each of said bars. The

frame is provided with a platform 3 on which is located a motor 4 andthe bearings 5 for, the shafts 6 and 7. As shown the two shafts areconnected together bythe beveled gears 8 and the shaft 6 carries thetoothed wheel 9 which is connected with the driving wheel of the motorby the gear 1.0. The other shaft carries a toothed wheel 11. 12indicates the guiding roller which is of conical shape and which ismounted in the bearings 13 and 14 depending from the bottom of theframe. This roller carries a toothed wheel 15 and a chain 16 passes overthis wheel and the wheel 11 whereby the guiding roller will be rotatedfrom the motor. 17 indicates small wheels for tightening the chain. Thebearing 14 is movable so as to adjust the position of the small end ofthe guiding roller. As shown this bearingis formed on a bell crank lever18 which is pivoted to a support 19 and the end of this support isrounded to permit the axle of the roller to have movement about thesame. 20 are strips located on the roller for providing a grippingsurface thereon. To the underside of the bolster 2 is secured a numberof brackets 21 having notches 21 formed in their lower depending ends.22 is the packing roller provided with the shaft 23 which engages withthe notches 21 in the brackets. As shown the roller is made up of aplurality of roller elements 24, said elements being located between thebrackets as shown. 25 is a small roller carried by the projecting bars26 on the end of the frame and adapted to engage with the walls of thesilo to prevent the device from contacting therewith. It will be seenthat a space will be left adjacent the walls of the silo which will notbe packed by the rollers and to provide means for packing this strip Iemploy a narrow roller 27 carried by a bar 28 which is slidably carriedby the brackets 29 on the frame. The outer end of said bar, whichcarries the roller, is bent to throw the roller wheel beyond the frameand a-supporting bar 30 is secured to this bar adjacent the roller andhas its other end pivoted in a bracket 31 carried at the end of theframe. To hold the roller 27 in its outermost position where it willengage with the material adjacent the walls of the silo I provide aspring 32 engaging a'roller 32 on the bar 28 carrying the roller andhaving its other en d bearing against a bracket 33 located on the frame.It will thus be seen that this spring tends to move the barlongitudinallyv to throw the Wheel 27 against the wall of the silo. Whenthe device is placed in the silo and assembled and the motor started theguid.

tion that the advantages and novel features of my invention Will bereadily apparent.

What I claim is 1. A device of the class described con1- prising aframe, a conical guiding roller Copies of this patent may be obtainedfor thereon, a packing roller extended at right angles to the conicalroller, means for r0- tating the rollers and means for adjusting theposition of the guiding roller on the frame for guiding the device indifferent sizes of circles. 1

2. A device of the class described comprising a frame, guiding andpacking rollers carried thereby, means for adjusting one end of theguiding roller, a second packing roller, a longitudinally movablesha'ftcarrying the same and a spring engaging With said shaft and tendingtomove the same outwardly.

In testimony whereof I affix my signature.
